I have what some of you might consider a very silly question as it is one that has probably been asked for decades.... How do they film people/objects in front of a mirror without the camera and crew showing up in the reflection? With today's technology a question like that would be a no-brainer. However, the reason I even bring this question up is that I have been watching a lot of classic film and television lately on DVD and always take notice of scenes involving mirrors. Back in the early days of cinema I am certain that lensing in front of mirrors became a challenge for filmmakers. Just curious.
